Abstract: A compressible multiphase flow numerical scheme, induced from the multi- component diffuse interface model
with arbitrary number of materials, is established to simulate the interaction between distinct materials under extreme
conditions. A robust, low dissipation and high efficiency reconstruction method, the MTBVD (muscl thinc boundary variation
diminishing), is proposed with the aid of artificial intelligence technology, which can adaptively select the most suitable
reconstruction method in the essential regions such as shock wave, contact discontinuity and material interface, and can
achieve the minimum global numerical dissipation. Furthermore, it has a higher computational efficiency than the traditional
BVD (boundary variation diminishing) scheme. The automatic geometric modeling and grid meshing based on global
geographic information system, adaptive mesh refinement and large-scale parallel computing method are established to realize
the whole numerical simulation of shock wave propagation in complex terrain and real urban environments. Our schemes
allows for the effective simulation of intense blast wave scenarios on a large scale within intricate urban settings, employing
